Threat Detector
The Digital RF Threat Detector is a compact receiver for detecting RF transmitting devices. The module can be hand-held and battery powered, or wall mounted and powered via cable, depending on the application. Each detector is provided to monitor multiple frequency bands. When operating with the Digital RF Blackshadow jammer the jammer is turned on upon detecting a threat. The signal to activate the jammer is provided on a remote connector or via radio control.
In a quiet period the Threat Detector is in listening mode. On receiving a threat the frequency of the threat is detected and the jammer transmits for 15 seconds around the threat. After 15 seconds the Threat Detector listens and if the threat still exists the jammer transmits for another 15 seconds. This mode continues until the threat has ceased.
Smart Detector
The most effective jamming occurs when the frequency of the jammer is at or around the threat. The DRF Smart 
Detector detects a frequency through filters covering the bandwidth of each jammer plug-in. When a threat arises the synthesizer is set to transmit a jamming signal around the bandwidth of the threat frequency. The Smart Detector can detect multiple threat frequencies.
If during the listening mode the frequency of the threat changes the frequency of the jammer will follow the threat. If there is no longer a threat the Detector remains in listening mode and the jammer transmit amplifier is turned off to conserve the battery.
